BROSELEY SERIES
The Broseley series consists of deep, well and somewhat excessively drained soils formed in sandy alluvial deposits. Permeability is moderately rapid. These soils are on nearly level, undulating, and sloping natural levees or terraces of Late Pleistocene Age. Slope gradients range from 0 to 15 percent. Mean annual temperature is 59 degrees F, and mean annual precipitation is 50 inches.
TAXONOMIC CLASS: Loamy, mixed, superactive, thermic Arenic Hapludalfs
TYPICAL PEDON: Broseley loamy fine sand - on a 1 percent slope in a cultivated field. (Colors are for moist soil unless otherwise noted.)
Ap--0 to 10 inches; dark brown (10YR 3/3) loamy fine sand, light yellowish brown (10YR 6/4) dry; weak fine granular structure; very friable; many fine roots; slightly compact (traffic) pan-like layer in lower 3 inches; moderately acid; clear smooth boundary. (6 to 13 inches thick).
E--10 to 37 inches; brown (10YR 4/3) loamy fine sand; weak medium granular structure; very friable; common fine roots; common fine pores; thin (3 to 5 mm) dark brown (10YR 3/3) sandy loam lamellae at a depth of 12 to 16 inches; slightly acid; abrupt wavy boundary. (14 to 30 inches thick).
Bt1--37 to 50 inches; brown (7.5YR 4/4) fine sandy loam; few fine distinct grayish brown (10YR 5/2) mottles; weak fine subangular blocky structure; friable; few fine roots; few fine pores; thin dark brown (10YR 3/3) coatings (clay and organic) on faces of a few peds and bridging of sand grains; moderately acid; clear smooth boundary.
Bt2--50 to 57 inches; dark yellowish brown (10YR 4/4) fine sandy loam; many medium distinct light brownish gray (10YR 6/2) mottles; weak fine subangular blocky structure; friable; few fine roots; few fine pores; thin dark brown (10YR 3/3) stains or coatings (clay and organic) on faces of a few peds and bridging of sand grains; strongly acid; clear smooth boundary.
Bt3--57 to 63 inches; dark yellowish brown (10YR 4/4) fine sandy loam; few fine faint brown (10YR 5/3) mottles; weak fine subangular blocky structure; friable; thin dark brown (7.5YR 3/2) coatings (clay and organic) on faces of a few peds and bridging of sand grains; strongly acid; abrupt smooth boundary. (Combined thickness of the Bt horizons is 16 to 42 inches).
CB--63 to 75 inches; yellowish brown (10YR 5/4) loamy fine sand; massive; very friable (C); comprises 75 percent of the horizon; and dark yellowish brown (10YR 4/4) fine sandy loam lamellae (Bt); weak medium platy structure parting to weak fine subangular blocky; friable; consisting of 1/16- to 3/4-inch bands or strata alternating with thicker loamy fine sand strata; slightly acid.
TYPE LOCATION: New Madrid County, Missouri; about 1 1/2 miles north of La Forge; 400 feet west and 1,290 feet north of the southeast corner, sec. 27, T. 24 N., R. 14 E. Latitude 36 degrees, 40 minutes, 33.5 seconds N., longitude 89 degrees,33 minutes, 52.4 seconds W., NAD83
RANGE IN CHARACTERISTICS: Solum thickness ranges from 48 to more than 72 inches. The solum and underlying material have a high content of fine sand. Reaction ranges from strongly acid to slightly acid throughout the profile.
The A and E horizons have hue of 10YR or 7.5YR, value of 3 or 4; 6 or more dry, and chroma of 2 to 4 moist or dry. It is loamy sand, fine sand, or loamy fine sand. Depth to the top of Bt horizon is 24 to 39 inches.
The BE or BA horizon, where present, has hue of 10YR or 7.5YR, value of 3 to 5, and chroma of 3 or 4. Texture is similar to the A and E horizons.
The Bt horizon has hue of 10YR to 5YR, value of 4 to 6, and chroma of 3 to 6. It typically is fine sandy loam, loam, or sandy clay loam. Clay content commonly averages from 12 to 20 percent and ranges from about 9 to 25 percent. The Bt horizon commonly has mottles with hue of 10YR or 7.5YR, value of 5 or 6, and chroma of 2 or 3.
The CB horizon, when present, has lamellae of sandy loam or fine sandy loam. Some pedons have a C horizon with dominant texture of loamy sand or loamy fine sand.
COMPETING SERIES: These are no other series in the same family. Similar soils include the
Beulah,
Bosket, and
Farrenburg series. Beulah soils lack argillic horizons. The Bosket and Farrenburg soils have fine sandy loam A horizons and horizons above the Bt with textures finer than loamy fine sand.
GEOGRAPHIC SETTING: Broseley soils are on nearly level, undulating and sloping natural levees or terraces of Late Pleistocene Age. Slopes range from 0 to 15 percent, but slope gradients typically are 0 to 6 percent. Broseley soils formed in sandy alluvial deposits. Mean annual temperature ranges from 59 to 65 degrees F, and annual precipitation ranges from 45 to 55 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These include the competing
Bosket and
Farrenburg soils and the
Canalou,
Clana,
Dubbs,
Dundee,
Forestdale,
Malden, and
Scotco soils. Bosket soils are on similar positions. Farrenburg soils are in lower positions. Canalou and Clana soils are on nearly level areas below the Broseley soils and are wetter. Dubbs soils occur on similar landscapes but have finer textures in the upper 20 inches. Dundee and Forestdale soils occur on nearly level areas or in depressions below the Broseley soils and have finer textures in the upper 20 inches. Malden and Scotco soils occur above the Broseley soils and lack argillic horizons.
DRAINAGE AND PERMEABILITY: Well and somewhat excessively drained. Runoff is negligible to low depending on degree of slope. Permeability is moderately rapid. The saturated hydraulic conductivity is high.
USE AND VEGETATION: Almost all the acreage is cleared and cropped to soybeans, corn, cotton, small grains, grain sorghum, and some truck crops and fruits. Native vegetation is chiefly mixed hardwoods with native grasses in openings.
DISTRIBUTION AND EXTENT: The northern extent of lower Mississippi River Alluvial Valley, Southeast Missouri, and northeastern Arkansas. It is of moderate extent.

SERIES ESTABLISHED: New Madrid County, Missouri, 1974.
REMARKS: Diagnostic horizons and features recognized in this series are: ochric epipedon - the zone from the surface of the soil to a depth of 37 inches (Ap and E horizons); argillic horizon - the zone from approximately 37 to 63 inches
(Bt1, Bt2, and Bt3) horizons; the upper and lower boundary is not distinct because of lamellae in the soil profile; udic moisture regime.
